# FastAPI CLI { #fastapi-cli }

**FastAPI CLI** is a command line program that you can use to serve your FastAPI app, manage your FastAPI project, and more.

When you install FastAPI (e.g. with `pip install "fastapi[standard]"`), it includes a package called `fastapi-cli`, this package provides the `fastapi` command in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console

    String ROLE = ModelInterpolator.class.getName();

    /**
     * @deprecated Use {@link ModelInterpolator#interpolate(Model, File, ProjectBuilderConfiguration, boolean)} instead.
     */
    @Deprecated
    Model interpolate(Model project, Map<String, ?> context) throws ModelInterpolationException;

    /**
     * @deprecated Use {@link ModelInterpolator#interpolate(Model, File, ProjectBuilderConfiguration, boolean)} instead.
     */

We can use **OAuth2** to build that with **FastAPI**.

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.

var errNoSuchUser = errors.New("Specified user does not exist")

// error returned by IAM when a use a builtin IDP command when they could mean
// to use a LDAP command.
var errNoSuchUserLDAPWarn = errors.New("Specified user does not exist. If you meant a user in LDAP please use command under `mc idp ldap`")

// error returned when service account is not found

 * ### Username and Password
 *
 * Username and password are either present, or the empty string `""` if absent. This class offers
 * no mechanism to differentiate empty from absent. Neither of these components are popular in
 * practice. Typically HTTP applications use other mechanisms for user identification and
 * authentication.

  # from application to upstream provider such as the Google login page
  alwaysShowLoginScreen: false
  # Uncommend the passwordConnector to use a specific connector for password grants

# Instead of reading from an external storage, use this list of clients.
#
# If this option isn't chosen clients may be added through the gRPC API.

The following example submits WordCount code to the Scala shell. Select an input file for the Spark WordCount example. We can use any text file as input.

- Login as user **‘spark’**.
- When the job runs, the library can now use **MinIO** during intermediate processing.
- Navigate to a node with Spark client and access the spark2-client directory:

```
cd /usr/hdp/current/spark2-client
